Preparation
Blend, Thin, Chill
- Blend the base: In a blender or food processor, combine the avocado, yogurt, anchovies with their oil, capers, garlic, lemon juice, mustard, Worcestershire, and Pecorino Romano. Blend until smooth.
- Emulsify: With the blender running, drizzle in the extra-virgin olive oil until fully incorporated and glossy.
- Adjust the texture: Add buttermilk gradually until you reach your desired texture: thick and creamy for dip, or looser and pourable for dressing.
- Taste and balance: Add more lemon for brightness, or a little more yogurt or avocado to mellow the flavor.
- Chill: Cover and chill at least 30 minutes before serving so the flavors settle.
